Change model configuration to use Andy API

[Sweaterdog]

Just changed freeguy.json to use the Andy API instead of groqcloud, as llama.json already uses groqcloud. Andy API is maintained by the Mindcraft-CE team (riqvip, uukelele, MrElmida, and I).

The API doesn't need an API key, and allows for 1,000 free requests per day for "official" models which the Mindcraft-CE team provides.

Pull request overview

This PR updates the freeguy.json profile configuration to use the Andy API (a free service provided by the Mindcraft-CE team) instead of GroqCloud. The configuration changes from a simple string model identifier to a full model object with custom API endpoint and parameters.

Key changes:

• Migration from GroqCloud (groq/llama-3.3-70b-versatile) to Andy API (gpt-oss-120b)
• Updated configuration structure from string to object format with explicit API, URL, and parameter specifications
• Removed max_tokens parameter (8000) in favor of temperature parameter (0.7)

No, the Andy API requires a host name for the model, the model therefore needs to be openai/gpt-oss-120b

[mrelmida]

The system is modular, so we just need to include the andy.js file. I already have one made, so I will just make a PR.

Maybe the issue stems from openai/ being in the model name since prompter.js checks for openai/, and then sets to OpenAI defaults.
